在次领先的BFKL框架中强子对撞机喷流之间的间隙

Gaps between jets at hadron colliders in the next-to-leading BFKL framework

F. Chevallier, O. Kepka, C. Marquet, C. Royon

摘要:

我们研究强子-强子碰撞中的衍射事件,其中两个喷流被产生并被一个大的快度间隙分开。在微扰QCD中,在t通道中交换的硬色单重态对象,并负责快度间隙,是Balitsky-Fadin-Kuraev-Lipatov(BFKL)Pomeron。我们进行了一个唯象的研究,包括由于下一个领先的修正(NLL)。使用重整化组改进的NLL内核,我们表明,BFKL预测与Tevatron数据吻合良好,并提出预测,可以在LHC进行测试。

英文摘要:

We investigate diffractive events in hadron-hadron collisions, in which two jets are produced and separated by a large rapidity gap. In perturbative QCD, the hard color-singlet object exchanged in the t-channel, and responsible for the rapidity gap, is the Balitsky-Fadin-Kuraev-Lipatov (BFKL) Pomeron. We perform a phenomenological study including the corrections due to next-to-leading logarithms (NLL). Using a renormalisation-group improved NLL kernel, we show that the BFKL predictions are in good agreement with the Tevatron data, and present predictions which could be tested at the LHC.
